ELEVATOR FOR HARVESTE RS.

SPECIFICATION forming part of Letters Patent N 6. 372,889, dated November 8, 1887. v I Application filed Februaryll, 1887. Serial No. 227,314. (No model.)

T0 aZZ whom, it may concern:

Be it known that I, MILTON E. BENEDICT, of Perry, in the county of Wyoming and State of New York, have invented a new and useful Improvement in Elevators for Harvesters, of which the following is a full, clear, and exact description. I

The object of my invention is to provide a new and improved elevator for harvesters, which is simple and durable in construction and very effective in operation.

The invention consists in the construction and arrangement of parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of part of a harvester provided with my improvement. Fig. 2 is a sectional plan view of part of the same on lines a: w of Fig. 1, and Fig. 3 is a detail view of one of the cam-shoes. Fig. 4 is a front elevation of the elevator, with the slats or cover removed. Fig. 5 is a side elevation of one of the brackets and the chain-link upon which it is formed.

' The harvester A, of any approved construction, is provided with the usual endless belt, B, which delivers the grain from the cutters to the elevator O, to be transported upward to the binding-table. (Not shown.) The elevator O is provided with two shafts,D and E,of which the upper shaft, D, is provided with a pulley, D, connected by belt with a driving-pulley of the harvester. The shafts D and E are mounted in suitable bearings in the sides of the inclined elevator-frame F, and each shaft is provided near its ends with sprocket-wheels G, over which pass the sprocket-chains H. On suitable brackets, H, formed upon the outside of certain links, H, of the-sprocket-chains H,are journaled the bars or rods I, placed at suitable distances apart and running parallel with the shafts D and E. These brackets are merely apertured plates or cars secured to or formed integral with certain links of the chains H. Each of the rods I is provided with the teeth or prongs I, which carry the grain upward on the inclined slats F of the elevator-frame F.

The ends of the rods I are provided with shoes J, which are rounded attheir forward ends and provided with curved recesses J in their opposite ends. The shoes are at right angles to prongs I, and travel in tracks L on the in side of the end pieces of the elevator-frame. The outer parts of the tracks L are formed by the outer bars, L and the parallel inner bars, L". The inner portions of the tracks are formed between the movable bars L and the coveringslats F, the bars L forming the outer sections of the said inner portions of the tracks, as is clearly shown in Figs. 1 and 2. The upper ends of the bars L are rounded, as shown by dotted lines in Fig. 1, to facilitate the entrance of the shoes into the outer section of the track. The bars L are pivoted at their lower ends to the inner sides of the end pieces of the frame and form the movable sections of the inner portions of the track L, as above stated. When the shoes J travel upward on this portion of the track, they bear on the bars L, which are normally held in the positions shown by full lines in Fig. 1 by means of the cams N. The

cams N are secured to the shaft N, journaled in the ends of the frame underneath the bars L and operated from the outside. When the cams are operated to allow the bars L to be pressed downward by the weight of the grain on the prongs or fingers I,the shoes and prongs will assume the position shown by dotted lines in Fig. 1, thereby rendering the elevator inoperative until the bars L are again thrown upward by turning the shafts and cams. When the shoes J pass beyond the upper ends of the bars L, they assume horizontal position, which causes the prongs or fingers to be drawn beneath the slotted cover, the recessed ends of the shoes striking the shaft D and bearing thereon until the shoes engage the upper curved end of the bar L If the rear ends of the shoes were square or round, the said ends on striking the shaft D would turn the prongs 1 forward, instead of withdrawing them horizontally entirely within the frame. The grain is prevented from dropping off the prongs I by the endless belt P, placed parallel with the slats F, and the lower fold traveling in the same'direction as the prongs 1.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an elevator for harvesters, the combination of the elevator-frame, shafts D E, journaled in the opposite ends thereof, sprocket wheels on said shafts, the endless chains, the movable bars L and their operating mechanism, the transverse bars I, journaled on the chains, the shoes J, secured at their front ends to bars I, and having recesses J in their rear ends, and the prongs or fingers I, projecting outward from the bars I at right angles to the shoes, the recessed ends of the shoes being constructed to bear against the upper shaft, D, when passing over it, substantially as set forth.

2. The combination of the elevator-frame, the tracks L on the inside of the end pieces thereof, the movable bars L, pivoted at their lower ends to the inner sides of the end pieces of the frame and forming the outer section of the inner portion of the track, the upper and lower shafts, D E, having sprocket-Wheels, the endless chains H, the transverse bars I, journaled on the said chains and having on their ends the shoes J, traveling in said tracks and recessed at J, the fingers I, and the transverse shaft N, journaled in the end pieces of the frame and having cams N, acting against the bars L, substantially as set forth.
